One cannot opt-out of society (short of moving to a different society), but one interact with society (as a whole) only through laws, contracts and formalized/ritualized interactions. On personal level one does not interact with society, but with other persons. Probably tens or at most hundreds. And one can opt-out of each of such personal interaction (and perhaps find a differend set of persons to interact on personal level). And that is one of the most important personal freedoms.
